Answer: destroying energy
Step-by-step explanation:
The cell is the basic unit of life. It consists of several components such as
Nucleus,
Mitochondria: it helps in obtaining energy through lipid oxidation within its layer
Cytosol: It helps in releasing energy from glucose breakdown (glycolysis)
Vacuoles, endoplasmic reticulum also help in storing energy in cells of adipose tissues.
But, NONE of the cell components helps in destroying energy, since energy is needed and usually well-regulated.
